func From ¶

func From(ts uint64, rand uint32) ID

From returns an ID with ts timestamp in the first 8 bytes and rand in the last 4 bytes.

func FromString ¶

func FromString(hex string) (id ID, err error)

FromString unmarshals hex into id.

hex can be any valid hexadecimal number corresponding to len(id) bytes.

func New ¶

func New() ID

New returns a new id.
